Why Is White Smoke a Problem?

Your car’s emissions can tell you a lot about its performance. Since exhaust fumes are composed of byproducts from combustion in the engine, the fumes may have some color. Most of the time, the fumes should be visible or slightly grey.

Black white and blue smoke is not regular. This problem points to your car burning through too much oil. It’s sad when your engine burns; it loses the lubrication needed to protect engine elements from heat and friction. But there are other problems that you should worry about. Damaged cylinders, wrong oil, broken head gaskets, and more will be concerning.

Keeping your automobile in good shape is crucial. That’s why we must figure out what’s happening right now. Let’s talk about the reasons for cars smoking after an oil change.

Excess Oil In Sump

While driving down the road, you may see blue-white smoke in your car’s rearview mirror. Yes, it’s not good. Blue-white smoke indicates oil around the sump, usually caused by too much oil in the reservoir. If there are too many, it can cause problems. The best option for you is to remove some of the oil.

You Used The Wrong Oil

There are different grades of viscosity of engine oil for a reason. If you put the wrong type, it can cause complications. Additionally, the oil won’t burn properly, causing much of it to be wasted.

To avoid this problem, always consult the car manual or do a quick Google check before putting in oil. You should follow the manufacturer’s recommendations. It’s because the lousy oil grade can cause white smoke. Fortunately, this issue is relatively easy to correct.

A Cylinder Cracks

A cracked cylinder is a path where oil enters the engine, producing white smoke from the exhaust. Of course, white smoke isn’t the only symptom you’ll experience. Other symptoms include rough running, low coolant, engine misfires, burning gas in the cooling system, and flashing warning lights.

It would help if you had it checked by an auto technician because it can cause other severe problems.

Blow Head Gasket

Blow head gaskets are another reason that makes you nervous. Sometimes, white smoke indicates a problem with the cooling system. And it means exposing the coolant to high pressures and temperatures, like a blown head gasket seal. Moreover, if you believe a blown head gasket is the cause, it’s best to take your car to a professional.

Leakage Valve Stem Seal

When valve stems seals don’t work correctly, oil can enter the explosion chamber. There the engine oil burns and produces white smoke. This causes shows slowly so that you may notice this problem later. But you may see your acceleration power isn’t the same as before.

But the good news is that replacing the valve stem is simple. Small rubber pieces are located on both sides of the valve. To remove them, you will need a good pair of pliers. Optionally, take your vehicle to an auto body repair shop.
